Hmmm "plenty of others" .. or just "some others" Whats the stats? Lets start a Poll on the subject. What are the actual statistics?... Ive seen many many posts from others that have given up trying to get it to run or get it to make calls properly on the iOS and Symbian . My latest attempt was on a brand new iPhone4 with no other additional apps installed . Thus, there would be nothing on the phone to cause a problem other than the app itself.. And lets not forget those customers that just decided that its functionality was not quite up-there and went with another SIP client app.1. the MoIP app works for plenty of others
Thats good to know.. so that leaves out the Exetel provider as being the issue then... ?2. Exetel is a layer 2 provider of Optus HSPA which means they do their own backhaul, if anything the Exetel version is less stressed than the straight Optus version
Ok ..good to know. I do use a Billion router. These are basically shipped with no QoS or other setting by default, with no "help" pages to guide you like a netgear router has. I will work on the settings to improve it but my foremost objective is to get it working via 3G data connection in iPhone.3. one way audio is most often NAT related, very prominent when using wireless if your network is not configured correctly or you have problem hardware (aka some Billion routers) and can require some adjustment on your end, your other post where you mention you have the same issue with Acrobits does seem to suggest you have some problems on your end ...
Note: the router is not the problem because:
a. The one-way issues (if you want to call them that) are most repeatable (to date 100%) when using VoIP over the 3G exetel/optus service direct from the iPhone.
b. The voip service works better via the wireless router (also an exetel 3G service) when at home, huge echo but at least it works two-way.
Agreed, the Acrobits app itself seems to work ok for me to, but the voip calls made via Exetel SIP service do not..I use Acrobits also and find it to work very well
So ... having discounted the SIP client app, the Exetel layer 2 provision of Optus HSPA, and my router,
what other "links in the chain" are there to troubleshoot?
Perhaps the Exetel SIP Server ?
Again your thoughts are alway appreciated. (i'm also wondering if this subject could be better served in a different thread)
